[0002] The retaining structure, groundwater control, environmental protection and other measures required to ensure the safety and stability of the underground space formed by excavation from the ground during the construction of the underground structure are called foundation pit engineering. Foundation pit engineering is a systematic engineering that integrates geological engineering, geotechnical engineering, structural engineering and geotechnical testing technology. Its main contents include engineering survey, support structure design and construction, earth excavation and backfilling, groundwater control, information construction and surrounding environmental protection. The simplest and most economical way to construct a foundation pit is to excavate with slope, but it is often restricted by site conditions and surrounding environment. Therefore, it is necessary to design a support system to ensure the smooth progress of construction and better protect the surrounding environment. The main function of the support beam is to ensure good support for the inner wall of the foundation pit during the construction process.

[0003] However, the existing foundation pit support beams still have some shortcomings and areas for improvement during actual use. When supporting the inner wall of the foundation pit, the existing support beams need to measure the distance between the lower foundation pits before they can support it. Generally, fixed sizes and customization are required, which is more troublesome. In addition, different fixings are required to be used in conjunction with the support beams for foundation pit connections with different geological conditions. Most of the existing solutions adopt a connection structure, which is not flexible enough to use and has low overall strength during use. Therefore, technicians in this field provide a high-strength support beam for a foundation pit to solve the problems raised in the above background technology. Utility Model Content
